Bradley Shaffer, Molecular Phylogenetics and Evolution, describes a new subspecies of leopard frog has been found living exclusively in New York City. The researchers describe in the paper that the new frog has a distinctive croak, quite different from the two existing species of leopard frogs on the East Coast. The new frog is also stand-offish and tends to impotently honk their horns when stuck in traffic."Link to Original Source
